WINDOW -CONTROL MEANS.

Application led Hay 5,

To all whom it may concern:

Be it known that I, ANGELO ROBERT CLAS, a citizen of the United States,and a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a new7 and useful findow-Control Means, which invention isfully set forth in the following specifition.' i f This inventionrelates to window Vraising and lowering mechanisms, and particularly tothose of the cable type adapted for use in connection-with the windowsof closed auto-- mobiles or the like.

The object of the 4Vinvention is the provision of a mechanism of theclass described, which is simple, efficient and inexpensive inconstruction, is capable of being easily operated to raise or lower anassociated window, and adapted tobe inserted in or removed as a unitfrom the window casing with which associated.

Further objects and advantages of the invention will be apparent fromthe following detailed description thereof. l

While the invention in its/broader aspect is capable of embodiment innumerous forms, a preferred embodiment thereof is illustrated in theaccompanying drawings, in which,--

' Figure 1 is an elevation of a mechanism embodying the invention andassociated with a door and` slidable Window member of a closed vehicle,the door and-window member being fragmentarily shown with the windowmember partly lowered. Figure 2` is a vertical fragmentary section ofthe door and as? sociated window member taken on the line 2--2 in Fig.1,- with the mechanism embodyingthe invention in operative relationthereto',"'and Fig. 3 is an enlarged section of the mechanism on theline 3-3.

Referring to the drawings, 1 designates a frame or casing, in thepresent instance the door of a closed automobile, which is provided inits upper portion with a window opening 2 adapted to be closed by aslid'able glass or window member 3, and forming a chamber 4 in its lowerportion into which the window member may be lowered and in which thecontrol means embodying the invention is disposed. The door or casing 1is provided in the upper portion. of the chamber 4: at the inner sidethereof with the customary lock-board 5.

The mechanism embodying the inventionv includes a frame -plate 6, whichis secured 1924. Serial No. 710,973.

to the inner side of the lock-board 5, prefverably in spaced relationthereto by reason of the end edges of the plate being'` laterallyflanged and having feet .7 resting against the lock-board. The platefeet'7 are rigidly secured to the lock-board by screws 8. One end of theframe plate 6 is disposed near theh' `)rizontal center of the'windowmember 3 and is providedat such end with a downwardly projectingextension arm Qthat is braced at its lower end by being secured byscrews l0, or in any vother suitable manner, to the lower cross-bar 11of the door 1.

A vertical guide bar 12 is disposed adjacent toone side edge of theframe arm 9 and extends from near the upper edge of the.

plate 6`to near the lower end of the extension arm 9 in inwardlyspacedrelation thereto. This guide bar is secured at its upper end to aboss 13 projecting from the plate 6 and at its lower end to a boss 14projecting from a side extension or ear on the lower end portion of thearm 9. A slide 15 is guided by the bar 12 for recip-rocatory movementslongitudinally thereof'and has a stub shaft 16 projecting laterallytherefrom, and such sha-ft has a roller or enlargement 17 on its outerend on which the lower edge of the window member 3 is adapted to restnear its central portion. A hook finger 18 (Fig. 2) is secured'to thelower edge of the window member and extends down under the member 17 toretain the edge of the window member in engagement therewith.

The operating means for imparting raising or lowering movements to 'thewindow member includes a cable 20, which is fixedly connected to theslide 15, in the present instance j to the stub shaft 16 thereof, andextends upward therefrom to near the upper edge of the plate 6, thencepasses over a guide sheave 21 carried by a stub shaft 22 projecting fromthe plate, and thence passes down and under a drum 23, which is disposedat the same side of the plate 6 with the sheave 21 and is mounted on aStub shaft 24 projecting from the plate. The cable passes one or moretimes around the drum 23, and thence over,and one or more timesar0und,an operating drum or sheave 25. This drum is preferably smallerthan the drum 23 and is carried by..a drive sha-ft 26 jurnalled in theplate 6 and lock-.board 5, and is provided at the inner side of the doororcasing 1 with an operating crank or member 27. The cable 20 afterpassing from the operating drum 25 extends over the drum 23 and thendown to the lower end of the extension arm 9 around a guide sheave 28andl then up to the slide '15, attaching shaft 17 thereof. The guidesheave 28 is yieldingly mounted to maintain the cable taut and for suchpurpose is carried by a. fork 29 having a stem 30 projecting upwardtherefrom and slidingly mountedv in a bracket 31 on the extension arm 9.A coiled expansion spring 32 encircles the ystem between the bracket andfork to normally retain the sheave in outwardly extended position.

It is evident that a turning of the operating crank 27 will impartmovement to the cable 20 to effect a raising or lowering of the slidel5, and with it the window member 3, the slide 15 being guided in itsmovements by the guide rod 12. It is found in practice that in windowraising and lowering mechanisms of the cable type it is quite importantfor satisfactory operation to have the member which connects the cablewith the window member guided for true vertical sliding movements,instead of being free to swing in and out with the cable between theupper and lower guiding points thereof. This guiding means also preventsa tipping of the window engaging member due to the window weight beingapplied thereto in laterally spaced relation to the cable.

It is evident that I have provideda simple construction of windowraising and lowering mechanism which is composed of a few parts and isadapted to be inserted in or removed as a unit from the door or casingwith which associated.

I wish it understood that my invention is not limited to any specilicconstruction, arrangement or form of the parts as it is capable ofnumerous modifications and changes without departing from the spirit ofthe claim. y

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

The combination with a casing, and a member mounted for sliding movementin said casing, of a frame plate secured to the casing at one side ofsaid member and having an arm extending therefrom in a directionparallel to the movement of said'member, a cylindrical guide rod fixedat its ends to said plate and arm .respectively and extending parallelto the movement of the slide member at a side thereof, a slide having acurved portion engaging said cylindrical guide rod for movement thereon,thereby to permit slight lateral movement between the slide androd,means on said slide to support said slide member, a plurality of guidesheaves carried by said plate and arm, one of which acts as an operatingsheave, operating means connected to said operating sheave, and a cableguided for movements by said sheaves and actuated by a rotation of theoperating sheave, said cable having a iight portion parallel to andco-extensive with the permissible movements of the slide member andattached to said slide to move it therewith.

In l testimony whereof I have hereunto signed my name to thisspecification.

ANGELO ROBERT CLAS.
